从6名受试者的上切牙和下切牙的唇面获得1、3、5、7和9天龄的菌斑样品。对这些样品进行了奈瑟菌属、诺卡氏菌属、链球菌属、梭杆菌属、韦荣氏球菌属、放线菌属和棒状杆菌属含量测定。在斑块形成的早期阶段，链球菌，奈瑟氏球菌和诺卡氏菌似乎占主导地位，而9天后，链球菌，放线菌，韦荣球菌和棒状杆菌占主导地位。厌氧生物如韦荣球菌和梭菌的生长依赖于需氧和兼性生物的先前生长，从而导致菌斑厚度增加，产生适合厌氧生长的条件。
Plaque samples of 1, 3, 5, 7, and 9 days of age were obtained from the labial surfaces of the upper and lower incisor teeth of 6 subjects. These samples were assayed for their content of Neisseria, Nocardia, Streptococcus, Fusobacterium, Veillonella, Actinomyces, and Corynebacterium. During the early stages of plaque formation, streptococci, neisseriae and nocardiae appeared to predominant while, after 9 days, streptococci, actinomyces, veillonellae and corynebacteria predominanted. Growth of anaerobic organisms such as veillonellae and fusobacteria was dependent upon prior growth of aerobic and facultative organisms with a resultant increase in plaque thickness yielding conditions suitable for anaerobic growth.
